I heard about this from @ralekseenkov. TDGotchi is an Eclipse plug-in that creates a virtual pet, like the old Tamagotchi, except that this one doesn’t thrive on simulated feedings. It thrives on watching you fix failing unit tests and do refactoring. Conversely, if you let your tests continue to fail, TDGotchi gets sicker and sicker. Don’t let this happen!
